From: Liam Girdwood Date: Wed, 7 Mar 2012 16:32:59 +0000 (+0000) Subject: ASoC: dapm: Add platform stream event support X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d9b0951b96e4ee0d22fae0a30f0b53354ca541cd;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git ASoC: dapm: Add platform stream event support Currently stream events are only perfomed on codec stream widgets only. There is now a need to be able to perform stream events on platform widgets too. e.g. we have the ABE platform driver with several DAI links to dummy codecs. We need to be able to perform stream events on any of the dummy codec DAI links. This patch also removes the snd_soc_dai * parameter since it's already contained within the rtd * parameter. Finally makle stream event return void since no one checks it anyway.
